Hello fellow flat earthers, just wondering how big or small the galaxy is? please give me a real answer not "infinite". 
I'll answer in terms of the universe instead of galaxy, because [as far as I can tell] the galaxy is just an arbitrary boundary, which has no real meaning. Universe we understand to be all of material existence.
People, like Baby Thork, may choose to believe in black holes, and think they know how close or far stars are, good for them. I don't claim to know that, but even so, thought I might do a forum post, since the question is interesting to think about. Hope that's OK? I certainly don't want to hurt anyone's feelings.
In terms of the universe (all of material existence) I actually believe it is essentially infinite. Because for anything to be defined, it must be defined in terms of something. It needs to have boundaries. So whatever is outside of that boundary is still by definition part of the whole.
This is a paradox, and maybe you feel it's not a real answer. Yet, I believe humans have limits on what we are able to understand. The true nature of the universe may never be understood. Or if somebody could understand It's not likely they would be able to express it in words (Or in a forum post)
